Thank you! This is exactly what I need. The 17 pages in the PERLDOC lib
info on Getopt::Long were a bit daunting/intimidating and for me like
driving a nail with a shotgun This sample code gives me a really
good example that shows the concept! Thank you for sharing it!

Richard here is an example of code that gets the switch variables from
the command line and checks it before continuing with the script. The
shift function is operating on the @_ array and the @_ array contains
the parameters passed to that subroutine from the command line(reference
perlvar).
my $switch = shift;
if($switch eq "" or $switch =~ /-u/i) {
print "$usagestring";
exit 1;
} elsif ($switch =~ /-p/i) {
$portnum = shift;
} elsif ($switch =~ /-d/i) {
$dbalias = shift;
} else {
print "Invalid argument passed. Try again.\n$usagestring";
exit 1;
}
Hope it helps.

Subject: How to use command-line switches...
I have a case where I need to use a command-line switch such as -X or /x
Could anyone help me with information as to how I read this into a perl
script and test it - along the lines of "if "/x" then..." ??
I've searched but can't seem to find any concrete example that a newbie
like me can use as a sample.
Thank you!!

RE: slash
Susan, Try: $dir = '//ITC/home/techs'; Your first example should have worked. You didn't need to put additional set of quotes around the string like you did in the latter examples. -Original Message- From: Susan Aurand [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 25, 2003 9:34 AM To: beginners Subject: slash If I want the following field to contain forwarded slashes - this is for a linux box, as follows. $dir="//ITC/home/techs"; How do I get the forward slashes in there? I have tried: $dir ="'//ITC'"; $dir ='"//ITC"'; $dir =`"//ITC"`; Nothing works. Help.

Subject: system function
I'm trying to execute a perl script with
system("sendscript.pl");
I also tried exec("sendscript.pl");
Both of these return Error: No such file or directory
The sendscript.pl is in the same directory as the script.
What am I doing wrong?

RE: Perl -w odd error
You need to do a loop of some sort and extract the data from the file try:
open (CNTFILE, "${OUTPUTFILE}") or die "Can't open ${OUTPUTFILE} : $!";
for ($i= 0; ; $i++){
$file_date = $_;
$FILE[$i]= $file_data;
}
close(CNTFILE);

Subject: Perl -w odd error
Folks,
I have the following block of code:
open (CNTFILE, "${OUTPUTFILE}") or die "Can't open ${OUTPUTFILE} :
$!";
@FILE=;
close(CNTFILE);
Which reports this warning:
Name "main::CNTFILE" used only once: possible typo at ./OrderTakingTree.pl
line 151.
I am just opening the file, slurping it in and closing it. Whats the prob?
-Ron
